I am going to share my experience about Bsnl 3G sim.Iam from orissa kendrapara district. I am using this sim in my Samsung galaxy core 2.It was giving me real 3g speed.I always get the download speed of 2 to 3mbps, but now I have shifted to other area and now the speed has reduced.iam not getting good network coverage and the speed which before I was getting.It is working like 2G.The speed which iam getting is 150kbps. I also talk to the customer executive, but no one listend to me.Some said clear your cookies data, so you will get better speed and some said remove your battery and sim card for sometime, Then again restart your phone.But none of the trick worked.I think it is due to the network problem.The tower signal cannot be reached in my area.Not only me all my neighbourhood are also using bsnl sim and they are not getting enough speed.Anyways iam happy with this much of speed
